NFA Doent work

Hi m new in this forum and I install NFA trial as per userguide to test it, all are going well but there is no router present in my devics list even when i select for new devices it returns:
No Router is currently exporting NetFlow packets to NetFlow Analyzer.
So kindly tell me how can I resolve this issue..........
